Expand cut block when navigating from search bar

[apervushin1]

Hi, I've found an issue with cut and search.

1. I search some text via diplodoc search bar
2. Search result located inside cut block
3. I navigate to the search result
4. Page is opened but cut was not expanded, so I don't see found text

I had to expand all cuts on this page and search again via Ctrl+F.
